NEMIX RAM 128GB DDR5 4800 CL40 1.1V 4Rx4 ECC RDIMM server RAM

NEMIX RAM 128GB DDR5 4800 Server Module

This NEMIX RAM module provides 128GB of DDR5 memory rated at 4800 MT/s with a CL40 latency and 1.1V operation. It uses a 288-pin RDIMM form factor with a 4Rx4 rank configuration and on-board ECC. The registered buffer helps maintain signal integrity across the memory bus. It is built with major OEM DRAM chips from Samsung, Micron or Hynix.

Suited for Dell PowerEdge R7625 capacity upgrades

This module targets administrators expanding memory in a Dell PowerEdge R7625 rack server where the qualified part number MR38400-744K1 is required. The registered ECC design matches the platform's requirements for error correction and command buffering. Builders using consumer motherboards, laptops or non-registered DIMM slots cannot use this memory. Systems limited to lower densities or different rank structures should look elsewhere.

128GB 4Rx4 density decides fit

The single most decisive specification is the 128GB capacity organised as a single 4Rx4 rank. The memory controller and BIOS must explicitly support this density and rank geometry for the module to initialise. Verify the server's qualified vendor list and maximum supported rank per channel before purchase. If the platform only accepts 1Rx4, 2Rx4 or lower capacities, this DIMM will not function.
